Advertising and marketing by the alcohol industry serve to normalise alcohol use, with exposure to alcohol advertising linked to earlier and riskier drinking among young people. Advertising that portrays alcohol use in and around waterways is of particular concern, with one in five fatal drownings being associated with alcohol.
Reasons for Th2 skewing in IgE-mediated food allergies remains unclear. Clinical observations suggest impaired T cell activation may drive Th2 responses evidenced by increased atopic manifestations in liver transplant patients on tacrolimus (a calcineurin inhibitor). We aimed to assess differentiation potential, T cell activation and calcium influx of naïve CD4+ T cells in children with IgE-mediated food allergies.
Food environments are significant drivers of obesity and diet-related diseases, making them key targets for interventions that support healthier food choices. The role of Local Government Authorities is pivotal in shaping community food environments.
Infant growth trajectory may influence later-life obesity. Human milk provides a wide range of nutritional and bioactive components that are vital for infant growth. Compared to formula-fed infants, breastfed infants are less likely to develop later-onset obesity, highlighting the potential role of bioactive components present in human milk.
Physical constraints of small apartment kitchens and the influence of the surrounding community food environment may impact food practices of apartment residents. Social media portrayal of these features may influence public perception of apartment living.
Infant allergy is the most common early manifestation of an increasing propensity for inflammation and immune dysregulation in modern environments. Refined low-fibre diets are a major risk for inflammatory diseases through adverse effects on the composition and function of gut microbiota. This has focused attention on the potential of prebiotic dietary fibres to favourably change gut microbiota, for local and systemic anti-inflammatory effects.
Children are often exposed to unhealthy outdoor food advertisements during the school commute. This exposure can have negative public health consequences given childhood weight gain has been linked to the marketing of energy-dense and nutrient-poor foods. This study aimed to explore schoolchildren's lived experiences and attitudes towards outdoor advertising surrounding their schools.
Complementary feeding induces dramatic ecological shifts in the infant gut microbiota toward more diverse compositions and functional metabolic capacities, with potential implications for immune and metabolic health. The aim of this study was to examine whether the age at which solid foods are introduced differentially affects the microbiota in predominantly breastfed infants compared with predominantly formula-fed infants.
Physical activity is crucial for young children's health and development. Many young children do not meet the recommended 3 hours of daily physical activity, including 60 min of energetic play. Early childhood education and care (ECEC/childcare) is a key setting to intervene to improve children's physical activity. The Play Active programme is a scalable evidence-informed ECEC-specific physical activity policy intervention with implementation support strategies to improve educators' physical activity-related practices.
Little is known about how sun exposure may affect the maternal skin barrier during pregnancy when many hormonal and physiological changes occur. In this longitudinal observational study, 50 pregnant women were recruited at 18-24 weeks' gestation, 25 in summer-autumn, and 25 in winter-spring. At three time points in pregnancy at 18-24, 28-30, and 36-38 weeks' gestation, participants completed a validated sun exposure questionnaire and had skin permeability and surface pH measured on the volar forearm.
Developing dietary guidelines for lactating women presents significant challenges, due to limited evidence being available on their specific nutrient needs and the biological impacts of various dietary dimensions. Current dietary recommendations often rely on data from nonlactating women, leading to potential inaccuracies.
The dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.
Current methods for assessing the healthfulness of 24-hour movement behaviours (sleep, sedentary time, light physical activity, moderate-to-vigorous physical activity) use binary classifications that fail to capture their continuous and compositional nature. This study introduces a percentile-based scoring and visualization approach to evaluate the healthfulness of movement behaviour time-use compositions, using social-emotional development in early childhood as an example.

The school environment profoundly influences children's development, behaviours, and attitudes. This chapter delves into the relationship between school design and architecture, and their impact on bullying, victimisation, inclusivity, and student well-being. Research underscores the significant impact of school design on student social dynamics, advocating for collaborative efforts among stakeholders to craft effective anti-bullying policies.
There is a growing need for early biomarkers that may predict the development of atopic dermatitis (AD). As alterations in skin barrier may be a primary event in disease pathogenesis, epithelial cell (EC) cytokines expression patterns may be a potential biomarker in early life to target allergy preventive strategies towards "at-risk" infants. The aim of this longitudinal investigation was to examine from birth over the course of infancy levels of the EC cytokines: thymic stromal lymphopoietin (TSLP), interleukin (IL)-33, IL-25, and IL-17 in infants at high-risk of AD due to maternal atopy.
Food retail and food service outlets can be part of a chain, or independently operated. Chain food outlets are likely to have the most influence over community food environments but have not been routinely identified in studies which map and monitor access to food, highlighting an important knowledge gap. This study aimed to identify the food retail and food service outlets present within metropolitan Perth, including presence of chain and independent food outlets; and examine differences across local governments.
Early infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease
Promoting healthy eating and physical activity in early childhood education and care is recommended within guidelines and supported by health promotion programs; however, implementation is suboptimal. Evidence suggests implementation within the sector varies over time; however, this has not been empirically examined in relation to implementation barriers.
